Given the strong relationship between number line estimation accuracy and math achievement, might a computer-based number line game help improve math achievement? In one study by Rittle-Johnson, Siegler and Alibali (2001), a simple digital game called "Catch the Monster" provided practice in estimating the location of decimals on a number line. The authors found that improving number line estimation accuracy transferred to other conceptual skills, such as the ability to compare the magnitudes of different decimal values. To our knowledge, however, no research has yet demonstrated any benefits from improving number line estimation accuracy in the domain of fractions. As the first step in an ongoing research study to investigate the benefits of improving number line estimation skills with fractions, this paper presents preliminary findings gathered by a novel digital game, "Battleship Numberline". This study advances the area of number line research by demonstrating that students can make significant gains in estimation accuracy with just 20 minutes of game play.
